spain vacation tours

Do I need Schengen Visa for visiting 11 European countries?
I am a US citizen and am considering to book a 16 days tour for visiting 10 European countries:
(France, Belgium, Netherlands, Luxembourg, Germany, Austria, Italy, Vatican City, Monaco, Spain)
After that I will stay in the UK for about two months.
Do I need a Schengen Visa for the tour and my vacation in UK?
For both the Schengen countries and the UK a passport is enough, you will receive a stamp in your passport which is in lieu of a visa, and will allow you to travel in that respective area for 3 months each.
